Austrian bank supervisors have instructed the country’s banks to limit future lending in their east European subsidiaries, a further sign of the potential knock-on effects of the eurozone crisis for economies around the world.

The restrictions come as Austrian officials seek to defend the country’s AAA credit rating, amid concerns that the government might have to bail out its banks because of losses in central and eastern Europe, where they are the biggest lenders, and their exposure to Italy.

The moves by Austria, which appear to be unilateral, show how even the eurozone’s strongest economies are feeling the pressure of the sovereign debt crisis.

The three banks’ CEE exposure exceeds Austrian GDP, raising concerns that the government would be unable to bail them out if their loan portfolios turned sour. The announcement came just as the spreads of Austrian bond yields over German Bunds rose to record highs and was also designed to calm market jitters, a central bank official said.
